Question

所以我设置了一个MVC项目来搜索数据库并显示结果。

点击搜索按钮，页面就会重新加载。我出错的任何想法？

控制器

  public function search()
{
$txt = $this->input->post('search', true);
$this->load->model('post');
$data['searchbox'] = $this->post->search($txt);        //search is function on model
$this->load->view('/search', $data);
}

模型

    public function search($txt)
{
        $query = $this->db->query("SELECT * From st_posts");
        return $query->result();  
}

表单视图

<form action="<?php echo site_url('/search');?>" method = "post">
        <div class="form-group">
        <div class="col-md-8">
            <input type="text" name = "search" id="search" class="form-control" /> 
        </div>
           <div class="col-md-4">
            <input type="submit" value = "Search" class="btn btn-primary center-block" />
            </div>
        </div>
        </form>

结果视图

<table>
            <tr>
                <th>ID</th>
                <th>title</th>
                <tr>
                    <?php foreach($searchbox as $row)?>
                        <tr>
                          <td><?php echo $row->id;?></td>
                          <td><?php echo $row->name;?></td>
                        </tr>
                    <?php endforeach;?>
                </table>

你应该总是使用模型只是为了查询数据库，比如删除，搜索，添加，更新数据等。我总是像这样申请尝试以这种形式更新你的代码：

<强>控制器：这就是说我们在控制器上有一个这样的功能：

public function search()
{
    $txt = $this->input->post('search', true);
    $this->load->model('Your model that you want to search from');
    $data['searchbox'] = $this->yourModel->search($txt);        //search is function on model
    $this->load->view('pages/membership_area/search', $data);

}

<强>模型：这就是说我们在Model上也有这样的函数：

public function search($txt)
{
        $query = $this->db->query("SELECT * From TableName");
        return $query->result();  
}

查看：

<?php foreach($searchbox as $row)?>
<tr>
  <td><?php echo $row->id;?></td>
  <td><?php echo $row->name;?></td>
</tr>

希望它适合你：）

Codeigniter搜索只是重新加载页面
